TECHNICAL FIELD

This disclosure relates generally to cloud computing and multimedia editing.

BACKGROUND

Modern mobile devices (e.g., smart phones, tablet computers) often include an embedded camera that allows a user to take digital images or videos of spontaneous events. These digital images and video can be stored in an online database associated with a user account to free up memory on the mobile device. Users can share their images and videos with friends and family, and download or stream the images and videos on demand using their various playback devices. These embedded cameras provide significant advantages over conventional digital cameras, which are more bulky and often require more time to set-up a shot.

Despite the convenience of mobile device embedded cameras, there are many important moments that are not captured by these devices because the moments occur too quickly or the user simply forgets to take an image or video because they are emotionally caught up in the moment.

DETAILED DESCRIPTION Overview

A wearable multimedia device is a lightweight, small form factor, battery-powered device that can be attached to a user's clothing or an object using a tension clasp, interlocking pin back, magnet or any other attachment mechanism. The wearable multimedia device includes a digital image capture device (e.g., 180° FOV with optical image stabilizer (OIS)) that allows a user to spontaneously capture multimedia data (e.g., video, audio, depth data) of life events (“moments”) and document transactions (e.g., financial transactions) with minimal user interaction or device set-up. The multimedia data (“context data”) captured by the wireless multimedia device is uploaded to a cloud computing platform with an application ecosystem that allows the context data to be processed, edited and formatted by one or more applications (e.g., Artificial Intelligence (AI) applications) into any desired presentation format (e.g., single image, image stream, video clip, audio clip, multimedia presentation, image gallery) that can be downloaded and replayed on the wearable multimedia device and/or any other playback device. For example, the cloud computing platform can transform video data and audio data into any desired filmmaking style (e.g., documentary, lifestyle, candid, photojournalism, sport, street) specified by the user.

In an embodiment, the context data is processed by server computer(s) of the cloud computing platform based on user preferences. For example, images can be color graded, stabilized and cropped perfectly to the moment the user wants to relive based on the user preferences. The user preferences can be stored in a user profile created by the user through an online account accessible through a website or portal, or the user preferences can be learned by the platform over time (e.g., using machine learning). In an embodiment, the cloud computing platform is a scalable distributed computing environment. For example, the cloud computing platform can be a distributed streaming platform (e.g., Apache Kafka™) with real-time streaming data pipelines and streaming applications that transform or react to streams of data.

In an embodiment, the user can start and stop a context data capture session on the wearable multimedia device with a simple touch gesture (e.g., a tap or swipe), by speaking a command or any other input mechanism. All or portions of the wearable multimedia device can automatically power down when it detects that it is not being worn by the user using one or more sensors (e.g., proximity sensor, optical sensor, accelerometers, gyroscopes). In an embodiment, the device can include photovoltaic surface technology to sustain battery life and inductive charging circuitry (e.g., Qi) to allow for inductive charging on charge mats and wireless over-the-air (OTA) charging.

The context data can be encrypted and compressed and stored in an online database associated with a user account using any desired encryption or compression technology. The context data can be stored for a specified period of time that can be set by the user. The user can be provided through a website, portal or mobile application with opt-in mechanisms and other tools for managing their data and data privacy.

In an embodiment, the context data includes point cloud data to provide three-dimensional (3D) surface mapped objects that can be processed using, for example, augmented reality (AR) and virtual reality (VR) applications in the application ecosystem. The point cloud data can be generated by a depth sensor (e.g., LiDAR or Time of Flight (TOF)) embedded on the wearable multimedia device.

In an embodiment, the wearable multimedia device includes a Global Navigation Satellite System (GNSS) receiver (e.g., Global Positioning System (GPS)) and one or more inertial sensors (e.g., accelerometers, gyroscopes) for determining the location and orientation of the user wearing the device when the context data was captured. In an embodiment, one or more images in the context data can be used by a localization application, such as a visual odometry application, in the application ecosystem to determine the position and orientation of the user.

In an embodiment, the wearable multimedia device can also include one or more environmental sensors, including but not limited to: an ambient light sensor, magnetometer, pressure sensor, voice activity detector, etc. This sensor data can be included in the context data to enrich a content presentation with additional information that can be used to capture the moment.

In an embodiment, the wearable multimedia device can include one or more biometric sensors, such as a heart rate sensor, fingerprint scanner, etc. This sensor data can be included in the context data to document a transaction or to indicate the emotional state of the user during the moment (e.g., elevated heart rate could indicate excitement or fear).

In an embodiment, the wearable multimedia device includes a headphone jack connecting a headset or earbuds, and one or more microphones for receiving voice command and capturing ambient audio. In an alternative embodiment, the wearable multimedia device includes short range communication technology, including but not limited to Bluetooth, IEEE 802.15.4 (ZigBee™) and near field communications (NFC). The short range communication technology can be used to wirelessly connect to a wireless headset or earbuds in addition to, or in place of the headphone jack, and/or can wirelessly connect to any other external device (e.g., a computer, printer, laser projector, television and other wearable devices).

In an embodiment, the wearable multimedia device includes a wireless transceiver and communication protocol stacks for a variety of communication technologies, including WiFi, 3G, 4G and 5G communication technologies. In an embodiment, the headset or earbuds also include sensors (e.g., biometric sensors, inertial sensors) that provide information about the direction the user is facing, to provide commands with head gestures, etc. In an embodiment, the camera direction can be controlled by the head gestures, such that the camera view follows the user's view direction. In an embodiment, the wearable multimedia device can be embedded in or attached to the user's glasses.

In an embodiment, the wearable multimedia device includes a laser projector (or can be wired or wirelessly coupled to an external laser projector) that allows the user to replay a moment on a surface such as a wall or table top. In another embodiment, the wearable multimedia device includes an output port that can connect to a laser projector or other output device.

In an embodiment, the wearable multimedia capture device includes a touch surface responsive to touch gestures (e.g., a tap, multi-tap or swipe gesture). The wearable multimedia device may include a small display for presenting information and one or more light indicators to indicate on/off status, power conditions or any other desired status.

In an embodiment, the cloud computing platform can be driven by context-based gestures (e.g., air gesture) in combination with speech queries, such as the user pointing to an object in their environment and saying: “What is that building?” The cloud computing platform uses the air gesture to narrow the scope of the viewport of the camera and isolate the building. One or more images of the building are captured and sent to the cloud computing platform where an image recognition application can run an image query and store or return the results to the user. Air and touch gestures can also be performed on a projected ephemeral display, for example, responding to user interface elements.

In an embodiment, the context data can be encrypted on the device and on the cloud computing platform so that only the user or any authorized viewer can relive the moment on a connected screen (e.g., smartphone, computer, television, etc.) or as a laser projection on a surface. An example architecture for the wearable multimedia device is described in reference to FIG. 8.

In addition to personal life events, the wearable multimedia device simplifies the capture of financial transactions that are currently handled by smartphones. The capture of every day transactions (e.g., business transactions, micro transactions) is made simpler, faster and more fluid by using sight assisted contextual awareness provided by the wearable multimedia device. For example, when the user engages in a financial transaction (e.g., making a purchase), the wearable multimedia device will generate data memorializing the financial transaction, including a date, time, amount, digital images or video of the parties, audio (e.g., user commentary describing the transaction) and environment data (e.g., location data). The data can be included in a multimedia data stream sent to the cloud computing platform, where it can be stored online and/or processed by one or more financial applications (e.g., financial management, accounting, budget, tax preparation, inventory, etc.).

In an embodiment, the cloud computing platform provides graphical user interfaces on a website or portal that allow various third party application developers to upload, update and manage their applications in an application ecosystem. Some example applications can include but are not limited to: personal live broadcasting (e.g., Instagram™ Life, Snapchat™), senior monitoring (e.g., to ensure that a loved one has taken their medicine), memory recall (e.g., showing a child's soccer game from last week) and personal guide (e.g., AI enabled personal guide that knows the location of the user and guides the user to perform an action).

In an embodiment, the wearable multimedia device includes one or more microphones and a headset. In some embodiments, the headset wire includes the microphone. In an embodiment, a digital assistant is implemented on the wearable multimedia device that responds to user queries, requests and commands. For example, the wearable multimedia device worn by a parent captures moment context data for a child's soccer game, and in particular a “moment” where the child scores a goal. The user can request (e.g., using a speech command) that the platform create a video clip of the goal and store it in their user account. Without any further actions by the user, the cloud computing platform identifies the correct portion of the moment context data (e.g., using face recognition, visual or audio cues) when the goal is scored, edits the moment context data into a video clip, and stores the video clip in a database associated with the user account.

Example Operating Environment

FIG. 1 is a block diagram of an operating environment for a wearable multimedia device and cloud computing platform with an application ecosystem for processing multimedia data captured by the wearable multimedia device, according to an embodiment. Operating environment 100 includes wearable multimedia devices 101, cloud computing platform 102, network 103, application (“app”) developers 104 and third party platforms 105. Cloud computing platform 102 is coupled to one or more databases 106 for storing context data uploaded by wearable multimedia devices 101.

As previously described, wearable multimedia devices 101 are lightweight, small form factor, battery-powered devices that can be attached to a user's clothing or an object using a tension clasp, interlocking pin back, magnet or any other attachment mechanism. Wearable multimedia devices 101 include a digital image capture device (e.g., 180° FOV with OIS) that allows a user to spontaneously capture multimedia data (e.g., video, audio, depth data) of “moments” and documenting every day transactions (e.g., financial transactions) with minimal user interaction or device set-up. The context data captured by wireless multimedia devices 101 are uploaded to cloud computing platform 102. Cloud computing platform 101 includes an application ecosystem that allows the context data to be processed, edited and formatted by one or more server side applications into any desired presentation format (e.g., single image, image stream, video clip, audio clip, multimedia presentation, images gallery) that can be downloaded and replayed on the wearable multimedia device and/or other playback device.

By way of example, at a child's birthday party a parent can clip the wearable multimedia device on their clothing (or attached the device to a necklace or chain and wear around their neck) so that the camera lens is facing in their view direction. The camera includes 180° FOV that allows the camera to capture almost everything that the user is currently seeing. The user can start recording by simply tapping the surface of the device or pressing a button. No additional set-up is required. A multimedia data stream (e.g., video with audio) is recorded that captures the special moments of the birthday (e.g., blowing out the candles). This “context data” is sent to cloud computing platform 102 in real-time through a wireless network (e.g., WiFi, cellular). In an embodiment, the context data is stored on the wearable multimedia device so that it can be uploaded at a later time. In another embodiment, the user can transfer the context data to another device (e.g., personal computer hard drive, smartphone, tablet computer, thumb drive) and upload the context data to cloud computing platform 102 at a later time using an application.

In an embodiment, the context data is processed by one or more applications of an application ecosystem hosted and managed by cloud computing platform 102. Applications can be accessed through their individual application programming interfaces (APIs). A custom distributed streaming pipeline is created by cloud computing platform 102 to process the context data based on one or more of the data type, data quantity, data quality, user preferences, templates and/or any other information to generate a desired presentation based on user preferences. In an embodiment, machine learning technology can be used to automatically select suitable applications to include in the data processing pipeline with or without user preferences. For example, historical user context data stored in a database (e.g., NoSQL database) can be used to determine user preferences for data processing using any suitable machine learning technology (e.g., deep learning or convolutional neural networks).

In an embodiment, the application ecosystem can include third party platforms 105 that process context data. Secure sessions are set-up between cloud computing platform 102 and third party platforms 105 to send/receive context data. This design allows third party app providers to control access to their application and to provide updates. In other embodiments, the applications are run on servers of cloud computing platform 102 and updates are sent to cloud computing platform 102. In the latter embodiment, app developers 104 can use an API provided by cloud computing platform 102 to upload and update applications to be included in the application ecosystem.

Example Data Processing System

FIG. 2 is a block diagram of a data processing system implemented by the cloud computing platform of FIG. 1, according to an embodiment. Data processing system 200 includes recorder 201, video buffer 202, audio buffer 203, photo buffer 204, ingestion server 205, data store 206, video processor 207, audio processor 208, photo processor 209 and third party processor 210.

A recorder 201 (e.g., a software application) running on a wearable multimedia device records video, audio and photo data (“context data”) captured by a camera and audio subsystem, and stores the data in buffers 202, 203, 204, respectively. This context data is then sent (e.g., using wireless OTA technology) to ingestion server 205 of cloud computing platform 102. In an embodiment, the data can be sent in separate data streams each with a unique stream identifier (streamid). The streams are discrete pieces of data that may contain the following example attributes: location (e.g., latitude, longitude), user, audio data, video stream of varying duration and N number of photos. A stream can have a duration of 1 to MAXSTREAM_LEN seconds, where in this example MAXSTREAM_LEN=20 seconds.

Ingestion server 205 ingests the streams and creates a stream record in data store 206 to store the results of processors 207-209. In an embodiment, the audio stream is processed first and is used to determine the other streams that are needed. Ingestion server 205 sends the streams to the appropriate processor 207-209 based on streamid. For example, the video stream is sent to video processor 207, the audio stream is sent to audio processor 208 and the photo stream is sent to photo processor 209. In an embodiment, at least a portion of data collected from the wearable multimedia device (e.g., image data) is processed into metadata and encrypted so that it can be further processed by a given application and sent back to the wearable multimedia device or other device.

Processors 207-209 can run proprietary or third party applications as previously described. For example, video processor 207 can be a video processing server that sends raw video data stored in video buffer 202 to a set of one or more image processing/editing applications 211, 212 based on user preferences or other information. Processor 207 sends requests to applications 211, 212, and returns the results to ingestion server 205. In an embodiment, third party processor 210 can process one or more of the streams using its own processor and application. In an another example, audio processor 208 can be an audio processing server that sends speech data stored in audio buffer 203 to a speech-to-text converter application 213.

Example Scene Identification Application

FIG. 3 is a block diagram of a data processing pipeline for processing a context data stream, according to an embodiment. In this embodiment, data processing pipeline 300 is created and configured to determine what the user is seeing based on the context data captured by a wearable multimedia device worn by the user. Ingestion server 301 receives an audio stream (e.g., including user commentary) from audio buffer 203 of wearable multimedia device and sends the audio stream to audio processor 305. Audio processor 305 sends the audio stream to app 306 which performs speech-to-text conversion and returns parsed text to audio processor 305. Audio processor 305 returns the parsed text to ingestion server 301.

Video processor 302 receives the parsed text from ingestion server 301 and sends a requests to video processing app 307. Video processing app 307 identifies objects in the video scene and uses the parsed text to label the objects. Video processing app 307 sends a response describing the scene (e.g., labeled objects) to video processor 302. Video processor then forwards the response to ingestion server 301. Ingestion server 301 sends the response to data merge process 308, which merges the response with the user's location, orientation and map data. Data merge process 308 returns a response with a scene description to recorder 304 on the wearable multimedia device. For example, the response can include text describing the scene as the child's birthday party, including a map location and a description of objects in the scene (e.g., identify people in the scene). Recorder 304 associates the scene description with the multimedia data (e.g., using a streamid) stored on the wearable multimedia device. When the user recalls the data, the data is enriched with the scene description.

In an embodiment, data merge process 308 may use more than just location and map data. There can also be a notion of ontology. For example, the facial features of the user's Dad captured in an image can be recognized by the cloud computing platform, and be returned as “Dad” rather than the user's name, and an address such as “555 Main Street, San Francisco, Calif.” can be returned as “Home.” The ontology can be specific to the user and can grow and learn from the user's input.

Example Transportation Application

FIG. 4 is a block diagram of another data processing for processing a context data stream for a transportation application, according to an embodiment. In this embodiment, data processing pipeline 400 is created to call a transportation company (e.g., Uber®, Lyft®) to get a ride home. Context data from a wearable multimedia device is received by ingestion server 401 and an audio stream from an audio buffer 203 is sent to audio processor 405. Audio processor 405 sends the audio stream to app 406, which converts the speech to text. The parsed text is returned to audio processor 405, which returns the parsed text to ingestion server 401 (e.g., a user speech request for transportation). The processed text is sent to third party processor 402. Third party processor 402 sends the user location and a token to a third party application 407 (e.g., Uber® or Lyft™® application). In an embodiment, the token is an API and authorization token used to broker a request on behalf of the user. Application 407 returns a response data structure to third party processor 402, which is forwarded to ingestion server 401. Ingestion server 401 checks the ride arrival status (e.g., ETA) in the response data structure and sets up a callback to the user in user callback queue 408. Ingestion server 401 returns a response with a vehicle description to recorder 404, which can be spoken to the user by a digital assistant through a loudspeaker on wearable multimedia device, or through the user's headphones or earbuds via a wired or wireless connection.

FIG. 5 illustrates data objects used by the data processing system of FIG. 2, according to an embodiment. The data objects are part of software component infrastructure instantiated on the cloud computing platform. A “streams” object includes the data streamid, deviceid, start, end, lat, lon, attributes and entities. “Streamid” identifies the stream (e.g., video, audio, photo), “deviceid” identifies the wearable multimedia device (e.g., a mobile device ID), “start” is the start time of the context data stream, “end” is the end time of the context data stream, “lat” is the latitude of the wearable multimedia device, “lon” is the longitude of the wearable multimedia device, “attributes” include, for example, birthday, facial points, skin tone, audio characteristics, address, phone number, etc., and “entities” make up an ontology. For example, the name “John Do” would be mapped to “Dad” or “Brother” depending on the user.

A “Users” object includes the data userid, deviceid, email, fname and lname. Userid identifies the user with a unique identifier, deviceid identifies the wearable device with a unique identifier, email is the user's registered email address, fname is the user's first name and lname is the user's last name. A “Userdevices” object includes the data userid and deviceid. A “devices” object includes the data deviceid, started, state, modified and created. In an embodiment, deviceid is a unique identifier for the device (e.g., distinct from a MAC address). Started is when the device was first started. State is on/off/sleep. Modified is the last modified date, which reflects the last state change or operating system (OS) change. Created is the first time the device was turned on.

A “ProcessingResults” object includes the data streamid, ai, result, callback, duration an accuracy. In an embodiment, streamid is each user stream as a Universally Unique Identifier (UUID). For example, a stream that was started from 8:00 AM to 10:00 AM will have id:15h158dhb4 and a stream that starts from 10:15 AM to 10:18 AM will have a UUID that was contacted for this stream. AI is the identifier for the platform application that was contacted for this stream. Result is the data sent from the platform application. Callback is the callback that was used (versions can change hence the callback is tracked in case the platform needs to replay the request). Accuracy is the score for how accurate the result set is. In an embodiment, processing results can be used for a lot of things, such as 1) to inform the merge server of the full set of results, 2) determine the fastest ai so that user experience can be enhanced, and 3) determine the most accurate ai. Depending on the use case, one may favor speed over accuracy or vice versa.

An “Entities” object includes the data entityID, userID, entityName, entityType and entityAttribute. EntityID is a UUID for the entity and an entity having multiple entries where the entityID references the one entity. For example, “Barack Obama” would have an entityID of 144, which could be linked in an associations table to POTUS44 or “Barack Hussein Obama” or “President Obama.” UserID identifies the user that the entity record was made for. EntityName is the name that the userID would call the entity. For example, Malia Obama's entityName for entityID 144 could be “Dad” or “Daddy.” EntityType is a person, place or thing. EntityAttribute is an array of attributes about the entity that are specific to the userID's understanding of that entity. This maps entities together so that when, for example, Malia makes the speech query: “Can you see Dad?”, the cloud computing platform can translate the query to Barack Hussein Obama and use that in brokering requests to third parties or looking up information in the system.

Example Processes

FIG. 6 is flow diagram of a data pipeline process, according to an embodiment. Process 600 can implemented using wearable multimedia devices 101 and cloud computing platform 102 described in reference to FIGS. 1-5.

Process 600 can begin by receiving context data from a wearable multimedia device (601). For example, the context data can include video, audio and still images captured by a camera and audio subsystem of the wearable multimedia device.

Process 600 can continue by creating (e.g., instantiating) a data processing pipeline with applications based on the context data and user requests/preferences (602). For example, based in user requests or preferences, and also based on the data type (e.g., audio, video, photo), one or more applications can be logically connected to form data processing pipeline to process the context data into a presentation to be playback on the wearable multimedia device or another device.

Process 600 can continue by processing the context data in the data processing pipeline (603). For example, speech from user commentary during a moment or transaction can be converted into text, which is then used to label objects in a video clip.

Process 600 can continue by sending the output of the data processing pipeline to the wearable multimedia device and/or other playback device (604).

Architecture 800 may include memory interface 802, data processor(s), image processor(s) or central processing unit(s) 804, and peripherals interface 806. Memory interface 802, processor(s) 804 or peripherals interface 806 may be separate components or may be integrated in one or more integrated circuits. One or more communication buses or signal lines may couple the various components.

Sensors, devices, and subsystems may be coupled to peripherals interface 806 to facilitate multiple functions. For example, motion sensor(s) 810, biometric sensor(s) 812, depth sensor 814 may be coupled to peripherals interface 806 to facilitate motion, orientation, biometric and depth detection functions.

A computer program is a set of instructions that may be used, directly or indirectly, in a computer to perform a certain activity or bring about a certain result. A computer program may be written in any form of programming language (e.g., Objective-C, Java), including compiled or interpreted languages, and it may be deployed in any form, including as a stand-alone program or as a module, component, subroutine, or other unit suitable for use in a computing environment.

Suitable processors for the execution of a program of instructions include, by way of example, both general and special purpose microprocessors, and the sole processor or one of multiple processors or cores, of any kind of computer. Generally, a processor will receive instructions and data from a read-only memory or a random-access memory or both. The essential elements of a computer are a processor for executing instructions and one or more memories for storing instructions and data. Generally, a computer may communicate with mass storage devices for storing data files. These mass storage devices may include magnetic disks, such as internal hard disks and removable disks; magneto-optical disks; and optical disks. Storage devices suitable for tangibly embodying computer program instructions and data include all forms of non-volatile memory, including by way of example, semiconductor memory devices, such as EPROM, EEPROM, and flash memory devices; magnetic disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM disks.

One or more features or steps of the disclosed embodiments may be implemented using an Application Programming Interface (API). An API may define on or more parameters that are passed between a calling application and other software code (e.g., an operating system, library routine, function) that provides a service, that provides data, or that performs an operation or a computation. The API may be implemented as one or more calls in program code that send or receive one or more parameters through a parameter list or other structure based on a call convention defined in an API specification document. A parameter may be a constant, a key, a data structure, an object, an object class, a variable, a data type, a pointer, an array, a list, or another call. API calls and parameters may be implemented in any programming language. The programming language may define the vocabulary and calling convention that a programmer will employ to access functions supporting the API. In some implementations, an API call may report to an application the capabilities of a device running the application, such as input capability, output capability, processing capability, power capability, communications capability, etc.
